Ni-Zn ferrite of compositional formula Ni0.5Zn0.5Fe2O4 was prepared by co-precipitation method. The effect of heat treatment at 600, 800, 1000 and 1200oC on their structures and hence magnetic properties were investigated. Their phase analysis and morphological studies was done using XRD, FTIR, FT-Raman and SEM-EDAX. Room temperature magnetization loops of the prepared materials were recorded up to a maximum applied field of 15kOe to study the effect of structural variation on magnetic properties. Further, magnetization loops of Ni-Zn ferrite heated at 1200oC were recorded at 150K and 50K to investigate the variation of magnetic properties at low temperatures. Law of approach to saturation magnetization was applied to all the magnetization curves under investigation. The fitted parameters reveal information on the processes of magnetization, anisotropy constant, and saturation magnetization of Ni-Zn ferrites. Law of approach to saturation magnetization in the form = (1− /2) + was also found to be successfully applicable to magnetization curves of all the prepared Ni-Zn ferrites in room temperature as well as low temperatures. Its application and significant results were also discussed in detailed.

“…The parameter H R = 2A/M s R 2 c is the exchange field in the random magnetic anisotropy model (which is the theoretical basis for equation (1) [16]) associated with the constants A, M s and R cthe correlation radius of the local easy magnetization axis. In nanocrystalline alloys, this scale is usually associated with the size of a crystallite [16], in composites with a nanogranule size [22] in amorphous materials, it represents a certain measure of the average order [25]. In the case of our films, which occupy an intermediate position between nanocrystalline alloys and magnetic composites, as we will show below, this size shows some change with temperature.…”

Fe-Co alloys attracting interest due to their high magnetic induction and Curie temperature, were synthesized by an eco friendly electroless deposition with carbohydrates as reducing agents. It was shown that Fe1-xCox-C composite coatings retain high induction, while demonstrating an unusual behavior of magnetization at low temperatures. It was found that for each coating measured at different temperatures, there is a correlation between the local magnetic anisotropy constant K at a given temperature and the correlation radius of the local easy magnetization axis Rc. The functional type of this correlation is typical for nanoparticles or nanogranules in a composite, which made it possible to estimate the volume and surface magnetic anisotropy constants of metal granules of FeCo-C coatings. Keywords: magnetic anisotropy, FeCo-C coatings, electroless deposition, approach to magnetic saturation law.

“…Параметр H R = 2A/M s R 2 c представляет собой обменное поле в модели случайной магнитной анизотропии (представляющей собой теоретическую основу для уравне-ния (1) [16]), связанное с константами A, M s и R cкорреляционный радиус локальной оси легкого намагничивания. В нанокристаллических сплавах этот масштаб обычно связывают с размером кристаллита [16], в композитах с размером наногранулы [22] в аморфных материалах, он представляет собой некую меру среднего порядка [25]. В случае наших пленок, занимающих промежуточное положение между нанокристаллическими сплавами и магнитными композитами, как мы покажем далее, этот размер демонстрирует некоторое изменение при изменении температуры.…”
